Engineered to support auxiliary slurry management, dust control, and pressure conveying across conveyor lines.
Within heavy bulk material handling operations—such as coal wash plants, iron ore concentrators, and copper extraction facilities—conveyor belt systems transport millions of tons of dry, damp, or wet material daily. A major operational challenge is the inevitable spillage and run-of-mine dust washdown accumulation under these conveyor belts. Sumps located along conveyor corridors collect highly abrasive run-off containing heavy rock shards, chemical additives, and dense slurry solids. Without dedicated auxiliary slurry pumping systems, this spillage threatens to halt conveyor structures, damage motors, and violate environmental discharge regulations.
Shandong Zhangqiu Blower Co., Ltd. (ZCBC) integrates over 50 years of industrial fluid mechanics, air handling technology, and heavy-duty manufacturing to design auxiliary slurry systems that eliminate sump overflow, maintain conveyor uptime, and enable closed-loop solids recycle loops.
Founded as Shandong Zhangqiu Blower Works, we have scaled to become a globally recognized, publicly listed manufacturing giant.
Listed on the Shenzhen Stock Exchange (Stock Code: 002598) in July 2011, establishing a robust capital base to support large-scale technological innovations and international supply lines.
Operating two Sino-Japanese Joint-Ventures and a dedicated US branch—making us the first enterprise in China's blower and heavy fluid machinery industry to build overseas operations.

How ZCBC is redefining hydraulic wear life and system integration over the next decade.
Traditional high-chromium alloy liners fail rapidly when exposed to the continuous abrasive shear forces of conveyor spillage. Our technical roadmap prioritizes high-purity, sintered silicon carbide ceramic-lined slurry pumps. Sintered SiC provides near-diamond hardness, protecting fluid passageways from cavitation-induced micro-fractures and acidic mine water corrosion.
To reduce electrical footprint and mechanical loss, we are integrating permanent magnet synchronous motor (PMSM) direct-drive blowers and pumps. This removes belt/gearbox power losses, lowering auxiliary energy consumption by up to 20% in high-capacity continuous sumps.
Through our intelligent machinery initiatives, next-gen auxiliary pumps feature vibration transducers, bearing temperature monitors, and acoustic leakage sensors. Operators receive real-time telemetry, preventing catastrophic impeller failure before it occurs.
Deploying comprehensive engineering solutions for demanding process industries.
Managing conveyor tailing spillage, heavy medium washdown solids, and coarse refuse under-belt sumps. Ensuring zero overflow into drainage systems while recovering recyclable coal fines.
Pumping highly abrasive copper, gold, iron, and nickel ore slurries. Providing high-density slurry transport without impeller erosion or casing puncture issues.
Delivering high-efficiency aeration blower technologies (Roots and Turbo) coupled with waste treatment pump packages to manage industrial effluent, chemical dosing, and filter press feeds.
How ZCBC leverages advanced automation and strategically located manufacturing hubs to secure global supply lines.
Our machine shops are equipped with nearly 100 sets of imported precision equipment, including five-axis CNC machining centers, high-capacity horizontal CNC lathes, three-axis coordinate measuring instruments, and ultrasonic non-destructive flaw detectors from Japan and Germany. These high-fidelity machines guarantee micro-level clearance control for industrial pumps and blowers.
By executing modern PLM (Product Life Cycle Management) systems alongside computerized CAM, CAPP (Computer-Aided Process Design), and CAT (Computer-Aided Testing), we accelerate production turnarounds. We offer custom 3D drawing reviews within 24 hours, and custom impeller designs are checked using Finite Element Analysis (FEA) and Computational Fluid Dynamics (CFD).
Reliable certifications backing every industrial component shipped worldwide.
ZCBC is ISO9001 (Quality), ISO14001 (Environmental), ISO50001 (Energy Management), and ISO10012 (Measurement) certified. All systems carry CE, 3C, and Mining Product Safety Mark certifications.
Backed by 69 authorized patents (including 5 major invention patents) covering countercurrent cooling, blower noise abatement, wear protection, special sealing configurations, and twin-lobe layouts.
Collaborative research partnerships with leading institutions, including Tsinghua University, Xi'an Jiaotong University, China University of Mining and Technology, and Shandong University.
Addressing the demands of project procurement managers, consultants, and lead engineering firms.
Procurement teams evaluate the long-term cost of operations rather than initial capital costs. By utilizing ceramic pump casings, the need for replacement parts is halved over a 36-month timeline, reducing operational downtime and lowering maintenance expenses.
Every mining sump and industrial facility has spatial constraints. ZCBC offers custom 3D drawing reviews within 24 hours. Customers can send rough drafts or target space measurements, and our design team will provide verified CAD/SolidWorks files for approval.
We supply turnkey systems, including the design, structural installation, electrical panel integration, and commissioning of comprehensive pneumatic conveying lines, industrial waste management packages, and MVR concentration loops.
Expert technical answers addressing common design, selection, and operational questions.
Conveyor belt operations generate spillage, dust cleanout, and washdown slurry that collects in under-belt sumps. Standard sump pumps quickly wear out due to abrasive runoff. A dedicated auxiliary slurry pump (particularly a ceramic-lined design) reliably pumps these abrasive solids, preventing sump overflow, rollers seizing, and conveyor belt damage.
Sintered silicon carbide ceramics feature a hardness near that of diamonds. Unlike chrome alloys, which erode under abrasive micro-cutting, ceramics withstand constant wear and remain chemical-resistant. This reduces wear rates by 3 to 5 times under abrasive slurry conditions.
In sumps containing heavy solids, settling can cause slurry compaction, leading to pump inlet blockage. Using a Roots Blower (such as our high-pressure SSR or ZZ series) to inject low-pressure air into the bottom of the sump agitates the slurry, keeping the solids in suspension and ensuring a steady flow to the pump intake.
Our design team provides custom 3D drawings (CAD/SolidWorks) within 24 hours of receiving target measurements. Thanks to our extensive production bases and global warehouse networks, common replacement parts (impellers, ceramic liners, shafts, and bearings) are available for immediate shipment.
